Cousins, who turns 30 in August, will become the rare starting quarterback to reach free agency in his prime after Washington arranged to acquire Smith from Kansas City in a deal that can become official when the trading period opens March 14. Once Cousins hits the market, he will be in position to choose from a range of suitors based on criteria that matters most to him, under the assumption that any team serious about signing him will pay him well.

It's unclear just how much Cousins might command, but one salary-cap analyst thought the deal could average more than $27 million per year, with a $50 million signing bonus and $90 million in the first three years. Cousins would then supplant Matthew Stafford as the highest-paid player in NFL history -- and subsequently lose that title when the next QB mega-deal is signed.
